Description
The TSL210 linear sensor array consists of five
sections   of   128   photodiodes,   each   with
associated charge amplifier circuitry, running from
a   common   clock.   These   sections   can   be
connected to form a contiguous 640 ?1 pixel
array. Device pixels measure 120 糾 (H) by
70 糾 (W) with 125-糾 center-to-center pixel
spacing. Operation is simplified by internal logic
that requires only a serial input (SI1 through SI5)
for each section and a common clock for the five
sections.
The device is intended for use in a wide variety of
applications including contact imaging, mark and
code reading, bar-code reading, edge detection
and positioning, OCR, level detection, and linear
and rotational encoding.
